Book Review 23 1 Feature Climate Change and Food Security R.Adhinarayanan * Climate Change temperatures over the past 50 years. Climate change is a significant and lasting change in Climate change is already showing us what's in store the statistical distribution of weather patterns over for our future. It keeps on giving warning signs that periods ranging from decades to millions of years. It we continue to neglect. Growing temperature, variation may be a change in average weather conditions, or in in duration and pattern of rainfall, increase in both the distribution of weather around the average conditions frequency and magnitude of natural calamities and above (i.e., more or fewer extreme weather events). In its all global level fight over natural resources- land, oil, recently released Fourth Assessment Report, the water, minerals etc. shows how precious these natural Intergovernmental Panel on Climate Change, of the resources are becoming. Not only Industries, natural United Nations, concluded there's a more than 90 percent resources are misused for agriculture, to keep in tune probability that human activities over the past 250 years with the global food needs. have warmed our planet. The industrial activities that our modern civilization depends upon have raised The challenge posed by Climate change to agriculture atmospheric carbon dioxide levels from 280 parts per also leaves a big question mark over future food security million to 379 parts per million in the last 150 years. and also on lives of billions farmers who depend on it. The panel also concluded there's a better than 90 percent Agriculture is now seen as an unviable livelihood option, probability that human-produced greenhouse gases such the fact being visible from migration of youths in villages as carbon dioxide, methane and nitrous oxide have towards nearby towns and cities, which is due to the caused much of the observed increase in Earth's fact that income from agriculture is becoming more https://www.e-education.psu.edu/geog438w/node/240 Courtesy: *Mr. R.Adhinarayanan, Team Leader, DHAN Foundation 2 and more unreliable.
